COMBINATION-DESK.

'SPECIFICATION forming' part OfV Letters Patent NO. 612,486, dated October 18, 18981. Application filed November 5,1897. Serial No. 657,487. (No model.)

T0 @ZZ wifi/077i, it may concern.'

Be it known that I, GEORGE WILLIAM CROCKER, Jr., acitizen of the United States, and a resident of Maple Valley, county of Otsego, and State of New York, have invented certain new and useful Improvements in Oombination-Desks, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof, in which similar letters of reference indicate corresponding parts.

This invention relates to improvements in combinationdesks; and the object thereof is to provide an article of this character containing a normally-inclosed type-writing machine and embodying in its construction the customary desk attachments and appliancessuch as drawers, filing-compartments, rbc.-

the type-writer being so arranged that it may readily be moved into and out of relative position when desired without interfering in any way with the general contents of the structure.

The invention will be hereinafter fully described, and specifically set forth in the annexed claims.

In the accompanying drawings, forming part of this specification, Figure 1 is a front elevation of my improved desk. Fig. 2 is a vertical sectional elevation taken on the line a: 0c of Fig. l and looking in the direction of Fig. 3 is a similar' view looking in the direction of the arrow 8. Fig. AAis a plan view of a portion of a desk, and Fig. 5 is a longitudinal sectional elevation taken on the line y y of Fig. 4. .1

In the practice of my invention I employ, primarily, an ordinary desk A, constructed with suitable drawers a and filing-compartments d of any suitable and adapted number and size.

Located centrally of the desk and mounted on the upper surface A' thereof is a box B. This said box is normally closed by means of a sliding door C, which engages vertical rails C'. Attached to each side wall b of the said box and leading outwardly therefrom is a rail D, which carries a sliding platform E, and mounted upon this platform .is any suit-able type-writing machine E.

Communicating with the sliding platform E is a verticallymovable platform F, which normally abuts against the front edge of the platform-E. The said platform Fis mounted upon cross-pieces f, and these said crosspieces have arms f' extended therefrom,which engage around vertical guide-pinsfi, whereby the platform can only move in a vertical direction. To maintain the platform in its normal upward position, normally-contracted coiled springs f3 are placed between the arms f' and the under surface of the plate A', stops f4 being supplied upon the under surface of the platform F to limit the upward motion thereof, whereby the said platform is normally` maintained even with the plate A to supply aperfectly flat upper desk-surface.

Abuttin g against the outer edge of the platform F and normally maintained upon a line therewith is a similar platform` G, this said platform being mounted upon cross-pieces g, Vwhich have arms g' extended therefrom engaging vertical guide-pins g2, springs. g3 being used for the purpose of maintaining the platform Gin its normal upward position, and stops g4 also being provided to limit the upward motion thereof for maintaining a smooth upper surface to the desk.

As a means for operating the platform 'F a lever I-I engages therewith by means of a toggle-joint ZL. This said lcveris fulcrumed upon a lug h', mounted upon a stationary platform A2, located beneath the plate A', comprising the upper surface of the desk, the free end h2 of the lever H being connected to a down wardly-extended rod I, which engages a lever J, the said lever being in engagement with a segmental rack K, which is supplied with a tooth 7o for locking the lever ina downward position.

Engaging the lever J is a cord L, which passes over a pulley Z, thence under a pulley Z', and over a pulley Z2, the ends thereof being connected to the sliding door C, whereby when the lever is pressed downwardly the platform F is moved below the surface of the plate A' and the door C is opened in an upward direction.

As a means for operating the platform G' a lever I-I, a toggle-joint h', and a rod I', the

roo

said rod engaging a lever J', which abuts against shoulders 7s and 7a2 of a segment K.

The levers J and J are respectively operated by means of handlesj andj'; but, if desired, pedals L7'2 maybe connected with the said levers, whereby they may be operated by means of lthe feet instead of the hands of the operator, this construction being illustrated by means of the dotted lines, Fig. 2 of the drawings.

Mounted to the left of the upper surface of the desk is a spring-actuated roller M, which has av blotter N coiled thereon. This said blotter is adapted to extend entirely across the desk when the type-writer is not in use,

and the end of the blotter is supplied with an eye n, adapted for engagement with a pin n upon the opposite surface of the desk,whereby the blotter may be normally maintained in a position extending entirely across the top of the desk. When it is desired to use the typewriter, the blotter is coiled upon the springactuated roller M. The lever J is then moved downwardly and brought into engagement with the shoulder 7a and locked there. This action carries the platform f downwardly and opens the door C, whereby the sliding platform E can be moved laterally until it rests upon the platform F, thus bringing the typewriter into position for use. If it is desired to still further extend the type-writer in a forward direction and bring it down to a lower level, the platform G is moved down to a position (illustrated by dotted lines, Fig. 3 of the drawings) by means of the lever J. The sliding platform carrying the type-writer can then be pushed forwardly until it rests upon the platform G, thus bringing the type-writer into the position illustrated by dotted lines, Fig. 3 of the drawings.

I do not confine myself to the specilic construction of desk-body as herein shown and described, as it is obvious that under the scope tion, consisting of a lever pivoted to the framework of the desk and fulcru med to an arm of said platform, the said arm having projections to which are 'affixed springs adapted to retain said platform in its normal upper position, suitable lugs to prevent a further upward movement of said platform, and an operating-lever pivotally connected with said lever, substantially as shown and described.

2. In a desk, the combination of two vertically-movable platforms adapted to support a type-writer at different elevations, a sliding platform adapted for carrying a type-writer and adapted to slide on or off said verticallymovable platforms, a box for normally inclosing the type-writer, spring-actuated levers for operating the vertically movable platforms, a sliding door comm unicatin g with said box for inclosing the type-writer, and a pulley or rope mechanism for operating the door, substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this lst day of November, 1897.
